You have images stored in HBase, which you need to retrieve from within your application. In
which format will your data be returned from an HBase scan?

A.
Uninterpreted array of bytes

B.
Java string literal

C.
Hexadecimal

D.
Blob datatype

Explanation:
HBase supports a “bytes-in/bytes-out” interface via Put and Result, so anything that
can be converted to an array of bytes can be stored as a value. Input could be strings, numbers,
complex objects, or even images as long as they can rendered as bytes.
